I definitely knew that Obi Wan and Anakin duelled in some sort of volcanic landscape and Annie fell into the lava and got burned so he had to wear the suit. I know I told people this in primary school before any prequels, where did I learn that?

The middle. 10 minutes was a bit of an exaggeration but I can find distinct accents less than 20 or 30 minutes away. They'll be similar compared to an accent from 100 miles away, but will have differences in certain sounds and dialect. There is an amazing amount of different accents. Look up accents from Newcastle, Liverpool, Yorkshire, Birmingham, London and Bristol. There are so many more and variations within those but those are good contrasts. And those are still all within England. Look up north and south Wales, and Edinburgh and Glasgow and Perth for Scotland.

The town I'm from is a higher income, upper middle class type of area so my accent is pretty generic, nobody can ever guess where I'm from. I've had Ireland, Canada, all over the UK. Nope, right in the middle. Just unplacable.
